CROSS REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. patent application Ser. No. 13/841,017, filed Mar. 15, 2013, which claims priority to U.S. Provisional Patent App. Ser. No. 61/622,377, filed Apr. 10, 2012, both of which are incorporated by reference in their entirety.

BACKGROUND Field of the Invention

The present invention generally relates to online search results.

Related Art

When a user or consumer wants to find something on the Internet, such as for a possible purchase of goods or services or just to find information, a search is typically conducted. The user enters one or more desired search terms that relate to the information sought by the user. The more terms and/or narrower the terms, the more focused the search results may be. When the search terms are submitted, a search engine or Internet Service Provider (ISP) performs the search and returns search results to the user.

Typically, search results are presented on a page with links the user can select to take the user to a particular site for more details. Such results may be presented in order of perceived relevance of the search terms, as determined by the search engine. For online shopping or purchases, specific merchants may have their sites or links listed earlier or featured in the search, e.g., as a paid service to the search engine or ISP. Another way to present search results for shopping is to show the user the search results within different categories or ranges to give the user a more manageable or informative result display. For example, a search for a product may show the user results within different price ranges. This may help the user identify which results would be relevant to the user.

Embodiments of the present disclosure and their advantages are best understood by referring to the detailed description that follows. It should be appreciated that like reference numerals are used to identify like elements illustrated in one or more of the figures, wherein showings therein are for purposes of illustrating embodiments of the present disclosure and not for purposes of limiting the same.

DETAILED DESCRIPTION

According to one embodiment, a service provider presents results from a search query with dynamic category ranges, with each category range having approximately the same number of items within the category range. In one embodiment, approximately the same is within 10%. In other embodiments, approximately the same is within 5%. The number may vary depending on the number of results and/or merchant specifications.

When a user submits a search query, the system or service provider determines the number of results returned for the query. The system then sets a number of ranges so that between ranges, in one embodiment, all have approximately the same number of results. Number of ranges could be limited by some predefined number. The ranges can be price, merchant rating (quantitative data), merchant sales of the item, category of item, overall, or other quantitative data. The system may determine a rounding factors set for each range. If a range has a large number of items, the user can select that range and see a finer set of ranges within that range. This can continue as needed or desired. Stores, merchants, or other online commerce sites may choose ranges to best suit their needs.

As a result, consumers may be able to better and more easily navigate search results because ranges will not have too many results (making it harder for the user to navigate through the results) or too few results (making it inefficient for the user to navigate through the results).

In one embodiment, a service provider receives a search query from a user through a user device, such as a PC, computing tablet, smart phone, etc. The search query may be for a specific merchant or a group of merchants. The search query may be one or more key words, along with any other search limiters, such as price, etc. For example, the user may enter “blue shirt.”

The service provider or system accesses a database, cloud, or memory containing available or offered items/services from the merchant(s) and searches based on the user query. In the above example, the system searches for “blue shirt” and finds 98 items or results matching the search query.

In a typical process, the system may return the results within fixed ranges. For example, the fixed ranges may be price ranges of $0 to $9.99, $10.00 to $19.99, $20.00 to $29.99. $30.00 to $39.99, $40.00 to $49.99, and $50.00 on up. The results may show 0 items in the first four price ranges, 10 items in the next price range, and 88 items in the last price range. This may not be that useful to the consumer, as the consumer would need to select the last price range to see most of the results, which may make it difficult for the user to efficiently navigate through those results.

With reference to FIG. 4, in one embodiment, the system determines suitable attributes, or price ranges 40, such that an approximate same number of items 42 are within each price range. In this example, and for a given set of search results, the illustrated price ranges 40 may vary, for example, be $40.00 to $49.99, $50.00 to $54.99, $55.00 to $57.99. $58.00 to $59.99, $60.00 to $69.99. $70.00 to $74.99. $75.00 to $82.99, $83.00 to $85.49. $85.50 to $89.99, and $90.00 to $100.00, with each range having an equal or similar number of items, for example between 8 and 10 items as shown at 42 in FIG. 4.

The attached flowchart illustrates steps a service provider may perform in determining and/or setting ranges, according to one embodiment.

Thus, the user is presented with a more manageable set of results for navigation.

If the initial search results yielded a very large number of items, the system may still limit the total number of ranges to ten or some other number. In such a case, each range may still have a large number of items, say approximately 200. The user can select a desired range and have the system automatically create ten (or some other number) ranges again containing approximately the same number of items. In this example, each range may contain approximately 20 items. The system may continue to dynamically set ranges within each preceding range as suitable.

In another embodiment, instead of the system determining a suitable range or a number of ranges, the merchant may specify the number. This number may be the initial range or number, such that subsequent ranges are determined by the system for the approximately equal distribution of search results.

Note that although price ranges 40 are described above, other ranges or categories 40 may also be suitable, such as merchant rating (quantitative data), merchant sales of the item, category of item, overall, consumer reviews (e.g., stars), or other quantitative data.

FIG. 1 is a flowchart 100 for a process of setting ranges for search results, according to one embodiment and will be described in conjunction with the description below.

The following algorithm illustrates one embodiment for determining intervals.

1) The system receives a search request from a user or consumer, such as through a user device like a PC, smart phone, computing tablet, or the like. The search request may be accessed through an app or URL. The user may enter desired term(s) to describe what the user is searching for. The search may be for items, services, specific information about a topic, a question, etc. The system may be a service provider that provides search results to a user. After receiving the search request, the system performs the search, as is well known in the art of search engines, and arranges search results in ascending order, at step 102

2) The system calculates a number of intervals, at step 104, using the following formula:

$d = {{round}\left( \frac{{\max({results})} - {\min({results})}}{h} \right)}$ where max(results) and min(results) are the minimum and maximum data values, h is the interval width. Interval width h could be found using any well-known formula for calculation histogram bin width (for instance Scott's choice, Freedman-Diaconis' choice, etc.). In one embodiment, if d is bigger than predefined number of ranges (intervals), the system sets d equal to that number. The maximum number may be a number chosen by the system or the merchant in different embodiments. If max(results) and min(results) are equal, the system sets d equal 1 for only one interval. In that case, all the results are shown or presented to the user within one interval, at step 106.

3) If there is more than one interval (d greater than one), the system calculates a percentage of results per range, at step 108, using the following equation:

$\frac{100\%}{d} = {k\mspace{14mu}\%}$

4) The system calculates quantiles, at step 110, and calculates confidential intervals around quantiles (or quantile confidential intervals), at step 112, as follows:

-   -   a) The system finds p_(c). For c=1 to d−1,

$p_{c} = \frac{c}{d}$ is calculated;

-   -   b) The system finds quantiles k_(p) _(c) . For c=1 to d−1, k_(p)         _(c) =P_(c)*n is calculated, where n is the number of results.

c) The system calculates confidential intervals around quantiles, within which intervals' end points will be searching. Order statistics quantiles are distributed by binominal distributions with parameters n and p_(c). The system uses normal distribution approximation of binominal distribution with parameters N(np_(c), np_(c)(1−p_(c))). The system finds confidence intervals, with confidence level 1−α, for k_(p) _(c) , i.e. it finds r₁ ^(c) and r₂ ^(c), 1≤r₁ ^(c)<r₂ ^(c)≤n, such as probability what interval (r₁ ^(c), r₂ ^(c)) contain quantile k_(p) _(c) would be bigger than 1−α. P(r ₁ ^(c) <k _(p) _(c) <r ₂ ^(c))≥1−α, where α is predefined number, usually equal to one of the values 0.001, 0.005, 0.01, 0.05, 0.1, although other numbers may be suitable as well. In case of normal approximation, interval limits around quantile k_(p) _(c) could be found using: r ₁ ^(c) =[n*p _(c)+0.5−zα/2√{right arrow over (n*p _(c)*(1−p _(c)))}] r ₂ ^(c) =[n*p _(c)+0.5−zα/2√{right arrow over (n*p _(c)*(1−p _(c)))}] where zα/2 is the standard normal distribution's α/2 quantile and satisfies

${\varphi\left( {z\;\alpha_{/2}} \right)} = {1 - {\frac{\alpha}{2}.}}$ [*] is a ceiling function and [*] is a floor function. If

${{k_{p_{c}} - {\frac{n}{2d}}} > \left( {k_{p_{c}} - r_{1}^{c}} \right)},$ as determined at step 114, then use

${r_{1}^{c} = {\frac{n}{2d}}},$ at step 116, else use r₁ ^(c) value (step 118) calculated at step 112 (keep r₁ ^(c) from calculation above). If

${{k_{p_{c}} - {\frac{n}{2d}}} < \left( {k_{p_{c}} - r_{2}^{c}} \right)},$ as determined at step 114, then use

${r_{c}^{2} = {\frac{n}{2d}}},$ at step 116, else use r₂ ^(c) value (step 118) calculated at step 112 (keep r₂ ^(c) from calculation above).

5) Next, the system calculates a rounding factors set for each results' interval, at step 120. For every price interval (r₁ ^(c), r₂ ^(c)) the system finds rounding factor set R^(c). For k=└ log₁₀(results(r₂ ^(c))−results(r₁ ^(c))┘, the system creates rounding factor set R^(c)={└10*10^(k−1),5*10^(k−1),2*10^(k−1),1*10^(k−1)┘} for k>0.

If k=0, use R^(c)={10, 5, 2, 1}.

If k<0, use R^(c)={10*10^(k),5*10^(k),2*10^(k),1*10^(k)}.

In case when results(r₂ ^(c))=results(r₁ ^(c)), all results in interval (r₁ ^(c),r₂ ^(c)) are equal, single value could be used denote that interval.

6) The system searches for intervals' end points around quantiles. It starts a search close to the quantile k_(p) _(c) and monotonically expands to the interval limits around quantile k_(p) _(c) . Two cases are possible, as determined at step 122: a) quantile k_(p) _(c) is a positive integer, and b) quantile k_(p) _(c) is not a positive integer (e.g., is a positive rational number).

Case 1 (k_(p) _(c) is positive integer) (step 124):

For c=1 to d−1

For j=0 to r₁ ^(c) rt mid i=0 to r₂ ^(c)

In interval (k_(P) _(c) −j·k_(p) _(c) +i) the system searches for values, which rounding factor is one of elements from R^(c). If one of the values has been found, the system saves it and continues searching for values, which rounding factors are rest of elements from R^(c). The system stops looping if all values have been found.

Case 2 (k_(p) _(c) is positive rational number) (step 126):

For c=1 to d−1

Find k_(p) _(c) ^(lower)=[k_(p) _(c) ] and k_(p) _(c) ^(upper)=[k_(p) _(c) ].

For j=0 to r₁ ^(c) and i=0 to r₂ ^(c)

In interval (k_(p) _(c) ^(lower)−j·k_(p) _(c) ^(upper)+i) searches for values, which rounding factor is one of elements from R. If one of the values has been found, the system saves it and continue search for values, which rounding factors are rest of elements from R. The system stops looping if all values have been found.

7) The system uses optimization criteria to choose optimal end points for each result interval, at step 128. Let's say value_(c) ^(m) result interval end points found in step 6 and index_(c) ^(m) such as

${\max\limits_{\underset{{from}\mspace{14mu}{interval}}{{all}\mspace{14mu}{indexes}}}{{results}\mspace{14mu}\left( {index}_{c}^{m} \right)}} < {value}_{c}^{*}$ m = 1, …  , V, c = 1, …  , d − 1. For  c = 1  to  d − 1 Find  value_(c)^(*)  minimize $\min_{m}{{\frac{{index}_{c}^{m} - {index}_{c - 1}^{m}}{n} - \frac{k\mspace{14mu}\%}{100\%}}}$ and value_(c)^(*) < value  (r₂^(c) + 1) Other optimization criteria could be described as follows: Find value_(c)* which rounding factor is the biggest and index_(c)* satisfy

$\left( {\frac{{index}_{c}^{m} - {index}_{c - 1}^{m}}{n} - {\frac{k\mspace{14mu}\%}{100\%}*100\%}} \right) \in {{value}_{c}^{*} < {{value}\mspace{14mu}\left( {r_{2}^{c} + 1} \right)\mspace{20mu}{and}\mspace{20mu}\left( {{{k\mspace{14mu}\%} - {\tau\mspace{14mu}\%}};{{k\mspace{14mu}\%} + {\tau\mspace{14mu}\%}}} \right)}}$ where r=k %*θ and θ is some small user predefined number. If two values for one range satisfy optimization criteria, the system uses value with the biggest rounding factor.

8) Next, at step 120, the system creates price intervals or ranges for the results:

For c=1 to d

If c=1, then interval endpoint is value₁* and results per interval are index₁*.

If 1<c<d, then interval endpoint is value_(c)* and results per interval are index_(c)*−index_(c−1)*.

If c=d, then results per interval are n−index_(d−1)*.

If the prices in the interval around quantile are equal (results(r₁ ^(c))=results(r₂ ^(c))), skip that interval and continue with next quantile, using skipped quantile's upper confidential interval's limit as next quantile lower confidential interval's limit. If no endpoints have been found and (min(results)|=results(r₁ ¹)) and/or (results(r₂ ^(d−1))|=max(results)), search those intervals (min(results)−results(r₁ ¹)) and (results(r₂ ^(d−1))−max (results)) for end points.

Results are then displayed or presented to the user, such as on the user device, within the ranges or intervals.

 15. A non-transitory machine-readable medium having instructions stored thereon that, when executed by one or more processors of a machine, cause the machine to perform operations comprising: receiving a search query regarding a transaction from a user device; obtaining search results based on the search query, wherein an attribute is common to the search results and the search results have respective attribute values for the attribute; executing an algorithm that groups the search results into subsets defined by variable ranges, respectively, of available attribute values for the attribute, wherein the algorithm distributes the search results into the subsets such that (i) attribute values of all search results in each subset are within a respective variable range defining the subset and (ii) an equal or a similar number of search results is grouped into in each subset defined by a respective variable range, wherein the algorithm prevents any of the search results from being grouped into a subset having a number of search results that is greater than or less than the equal or a similar number of search results; generating a navigable graphical interface having selectable elements, wherein each selectable element represents a respective subset of the search results, wherein an interaction with each selectable element results in navigating to a different graphical interface corresponding to the respective subset of the search results; and causing, responsive to receiving the search query, the user device to present the navigable graphical interface for the transaction.
 16. The non-transitory machine-readable medium of claim 15, wherein the attribute comprises price and the variable ranges respective comprises price ranges.
 17. The non-transitory machine-readable medium of claim 15, wherein the attribute comprises a merchant rating and the variable ranges respectively comprises merchant rating ranges.
 18. The non-transitory machine-readable medium of claim 15, wherein causing the user device to present the navigable graphical interface for the transaction comprises: transmitting the navigable interface with the selectable elements to the user device for presentation.
 19. The non-transitory machine-readable medium of claim 15, wherein the operations further comprise: receiving, from the user device, a selection of variable range from the variable ranges; creating a new plurality of variable ranges within the selected variable range; and causing presentation of an indication of the new plurality of variable ranges.
 20. The non-transitory machine-readable medium of claim 15, wherein the operations further comprise: receiving, from the user device, a selection of a variable range from the variable ranges; and causing presentation of items within the selected variable range.
